Full Answer

The surface of the sun is actually the coolest part of the sun, with an average temperature of about 10,000 degrees Fahrenheit. Sunspots on the surface are believed to be even cooler, at about 8,000 degrees. The corona, located above the surface of the sun, reaches temperatures of almost 1,000,000 degrees. The core of the sun is the hottest part of the sun by far, with nuclear fusion producing temperatures in excess of 25,000,000 degrees. The sun is a relatively cool star, however, with some stars reaching stable temperatures of 200,000,000 degrees and supernova temperatures of up to 10,000,000,000 degrees.

  • Q:

    How does the sun work?

    A:

    The sun is a very large thermonuclear furnace where hydrogen is converted into helium at temperatures in the millions of degrees. It formed during the early period of the solar system, as gas and dust fell toward a common center of gravity and compressed until it was hot enough to sustain fusion.

  • Q:

    How many miles is the sun from Earth?

    A:

    On average, the sun is 92,960,000 miles from Earth. The Earth has an elliptical orbit, so this distance varies. At the closest point of its orbit, called perihelion, Earth is 91,000,000 miles from the sun. At aphelion, the furthest Earth gets from the sun, they are 91,402,500 miles apart.

  • Q:

    What makes up the sun?

    A:

    The sun is almost entirely composed of hydrogen and helium. Hydrogen accounts for about 75 percent of the sun's mass, with the other 25 percent being almost entirely helium. Other elements, such as oxygen and carbon, do exist in the sun, but at such low concentrations as to be insignificant.

  • Q:

    Where does the sun set?

    A:

    The sun appears to set when it vanishes over the western horizon as the Earth rotates away from the sun. Depending on the Earth's tilt at a particular time of year, the sun sets either slightly north or south of due west.
